as hereinafter described, whereby the ends of the last horizontal topfold of the Wrapper are engaged, or interlocked, with the end folds, sothat the folds are lrept in place and eilleet a secure #rapping or thebonbons, the improved feeding means e'llecting the feeding in such amanner that the bonbons, on their Way to the mould-Wheel, are lrept in.correct position and are eventually veryv securely and evenly Wrapped intheir Wrappers.

live Will describe with reference to the accompanying drawings, theconstruction of a machine in accordance with this invention.

Figures 1, 2, 3, l and 5, shew, in perspective, progressive stages ofthe Wrapping;v

Figure 1 shevving the Wrapper round three longitudinal sides of abonbon, Figure 2 sheiving the irst top longitudinal fold, Figure 3showing the second top longitudinal told, Figure 4l showing the rst endfold and Figure 5 shevving the second end fold. Figure 6 is a sideelevation, Figure 7 is a pian and Figure 8 is an elevation as seen 'tromthe side opposite to that shevvn in Figure 6, ot an apparatus inaccordance ivith this invention. Figure 9 is a side elevation and Figure10 is a plan of the apparatus for lccding the bonbons to the mould-Wheelshewn in Figures 6, 7, and 8. Figures 11 and 152 illustrate,respectively, the relative positions o the parts When a bonbon and itsWrapper are being fed to the vmould-Wheel and when the said bonbon andWrapper are being pushed into the mould, respectively. Figure 13 is anend view of Figure 12. Figure 14 is a vien7 showing the bonbon andv-,ripper advancing towards a stationary :folder ivhicn effects thesecond. top longitudy inn l The Wrappers A, in which the bonbons B,- areto be enclosed are fed, by an endless .band 3, towards the mould-wheel1, along a wrapper as it reaches the end of the trough 2 being engagedby a gripping device 4- on the mould-wheel 1, each gripping devicecon'iprising a fixed aw and a movable aw turi'iing on a stud on themould-Wheel 1 and having an arm provided with a roller acted upon by aspring tending to maintain the jaws closed, the said movable jaw beingopened at the proper times, to admit the forward end of the Wrapper asit is passing .frein the trouglii 2. In' the apparatus accor-(fling tothe present invention and as sheivn more particularly in Figures 9-and10 of the' accompanying drawings we provideI the known arrangement of amovable jaw 5 of the gripping device l with an abutment, or stop, 6 todetermine the position of the Wrapperri relatively to the mould. Themould with the Wrapper is then, by the movement of the mould-Wheel,brought into position to receive a bonbon B to be enclosed in theWrapper A..

The bonbons B are, as described in the specifications of the aforesaidpatents, placed in a trough 7, the bottom of Which is constituted by anendless travelling band 8- passing round pulleys one, 9 of which isshei'vn in the drawings mounted. on a shaft 10 and intermittentlypartially rotated by a paWl 11 (see Fig. 8) on a lever 12 looselymounted on the shaft 10 the said pavvlengaging a ratchet-Wheel 13secured to the said shaft. Vrllhe lever 12 is operated by a roller 16eccentrically mounted on a disc 14- secured to a shaft 15 which, roller16, actuates an arm 17 formed in one With the said lever 12. Rotarymotion is transmitted from the mould Wheel shaft 18, to the shaft 15 bya toothed Wheel 43, secured to the said shaft 18, which rotates, througha toothed pinion. 15, a `toothed Wheel 15b secured to the said shaft 15.The partial rotation of the pin 9 is timed so as to earryeach bonbon insuccession into position to be transferred by a reciijirocating plunger19, operated by a rocking arm 19, from the endless band 3 into a channel2O arranged. at right angles to the direction of mot-ion of the saidendless band.v rlhe rocking arm 19a is actuated at the proper times by a'face `cam 19h, secured to the main driving shaft of the 'apparatusWhich-engages with the antifriction roller 19, en lthe lower' end ofthearm 19a.

lin the/machine constituting the present invention and as moreparticularly illustrated Yin `Figures 10 of the accomforward bonbon ismoved towards the mouldwheel,tl1e said means consisting of an arm 22,pivotally mounted on a bracket 23,'secured to the frame of theapparatus, which arm is, Whilst the forward bonbon is being pushedtowards the mould-Wheel, caused to bear upon the upper face of the nextsucceeding` bonbon, this being effected by a cam 24, secured to a shaft18, and bearing upon an antifriction roller 26 carried by the said arm.The end of the said arm is preferably provided with a resilientbearing-piece to prevent the bonbons being damaged and to allow forvariation of the thickness of the bonbons which resilient bearing-piecemay consist of a spring-pressed plunger, or stem, 27 movable in asocket-piece 2S on the end of the arm 22, as shevvn inFigure 9 of theaccompanying drawings.

Each bonbon is, in accordance with this invention, when pushed from thetrough 7 into the channel 2O by the reciprocating plunger 19, preventedfrom adhering to the said plunger by a vhinged piece 29 which bears, bygravity, upon the upper face of the bonbon and to further preventL suchadherence the bearing end'of the pusher may be recessed, or equivalentlyformed, so that only its edges, or a small portion of the said end willbear against the bonbons.

lThe bonbons in succession are pushed from the channel 2O by areciprocating plunger 30 operatedby an arm, or lever, 31

which may be actuated by vany suitable means from the main shaft 32 ofthe apparatus. The side of the channel 20 opposite the plunger 30 isvconstituted byA a hingedpiece, or,-gate, 34 Which acts, in'conjunctionivith the plunger 30, to maintain the foremost bonbon in correctposition as it advances towards the mould; a projection 33 on the saidplunger v30 engaging With and turning the said hinged piece, or gate,out oi' the path of the said bonbon. kas it is being pushed by saidplunger into positionfto ybe operated by a ysucceeding plunger 35i Theplunger 35, by which ,the bonbons and the Wrappers are forced into themoulds,'is slidably mounted in a socket 36 formed in one with an ar1n37pivotally mounted on a stud 38. Astudv 39 projects from the plunger 35,through a slot in the socket 36 on which stud is an antifriction roller40 bearing on a cam 4:1, secured to a `Shaft 42, having a toothed Wheel3f secured thereto which is row tated, through a train of toothedWheels, 13a,

43h, 43, 43d and' 43e, from a toothed `Wheel l o n the shaft 18 of themould-wheel 1, rotated by a'pinion 45 on the main shaft The cam 4 1 istimed to act l in conjunction with a spring 14: to cause the plunger 35to slide, `at the proper times, to and fro, in the socket 36 to pressthe bonbon into the mold. The arm 37 carries an antifriction roller 16(see more particularly Figures 11, l12ffn1d lfvvhich Cir bears on a cani47, on a shaft 48 to which is secured one (43) of the said train oftoothed wheels. The cam 41, acts through the arm 37 to cause the soclret36 to swing so that the plunger 36 follows the path of the bonbon, whichis in position, with a wrapper, on the movable bottom 49 of the mould,which bottom is, at this time, level with, or slightly above, the topedge of the movable sides 50 of the said mould. At the time that theplunger 35 is over the bonbon, the cam 4'? allows the spring 44 to pressthe said bonbon and the bottom 49 of the mould downwards, the saidplunger pressing the bonbon, together with the wrapper, into the mouldas it passes beneath the socket 36, as shown in Figure 12, the wrapperbeing at this time disengaged from the gripping device 4 on themould-wheel 1 by which gripping device the wrapper was engaged to bringit into position to receive the bonbon. The engagement of the Wrappersby the jaws 5 of the gripper is effected. by a stationary projection 51(see Figures 6 and 9) on the frame of the apparatus against whichprojection an antifriction roller 52 on the tail of each movable jaw 5comes into contact as the mould-wheel rotates, so as to open the saidmovable jaw to receive the edge of the wrapper as it is brought forwardby the lever 53, the said jaw being closed by a spring 54 when theanti-friction roller 52 passes the projection 51. rlhe jaw remainsclosed while the mould wheel is moving' to bring the wrapper intoposition to receive the bonbon and just as the said bonbon is being`pressed into the mould, the antifriction roller 52 comes into contactwith another stationary projection 55 which causes the jaw to open andrelease the wrapper. After passing the projection 55 the aw closes andremains closed until it again comes into contact with the projection 51,all in accordance with the aforesaid former patents, and ylikewise inaccordance therewith by the insertion of the wrapper and bonbon into themould two opposite ends 56 and 57 of the wrapper are caused by the sidesof the mould to stand up above the top surface of the bonbon as shown inFigure 1 and Figure 12 of the accompanying drawings. As the mould-wheelcontinues to rotate, the rear upstanding end 56 of the wrapl per isfolded onto the bonbon by a folding device comprising an arm 5S (seeFigures 14, 1,5 and 16) mounted on a stud 59 project-ing from the frameof the apparatus on which arm is pivoted another arm 60 carrying thefolding blade 61 the arm 56, carrying the folding blade 61, is caused tooscillate on the stud 59 by cams 62 and 63 on a shaft 64 to which issecured the toothed wheel 43 to which rotary motion is transmitted fromthe toothed wheel 43 on the mould wheel shaft 18 by the train of toothedwheels 43a, 43D, and 43C. The arm 56 carries an antifriction roller 65which is caused to bear on the cam 62 by a spring 66 and the two cams 62and 63 are timed so that when the antifriction roller 65 is on thelowest part of the cam 62 the folding blade 61 has partially folded theend 56 of the wrapper onto the bonbon, the cam 63 will act on the arm 66and turn the blade 61 on its ivot whereby the said end 56 is laid ontothe bonbon, as shewn Ain Figure 2 of the accompanying drawings, the saidarm being then caused, by the cam 62, to oscillate in the reversedirection and become clear of the wrapper. A guard 67 is arranged topartially surround the mould-wheel against one ond of which, as themould wheel 1 rotates, the other upstanding end 57 of the wrapper comesinto contact and is thereby folded onto the end 56 previously foldedonto the bonbon as shown in Figure 3 of the accompanying drawings, andin accordance with the arrangement of the aforesaid prior patents.

r)Ehe first end-folds of the two laterally projecting ends of thewrapper are eifected by a folding device which acts to press the saidends onto a concentric plate, or guard, 91 (see Figures 17, 1S and 19 ofthe accor. panying drawings) carried in any suitable manner by the frameof the apparatus. The said folding device is illustrated as beingsimilar in construction, and as being operated in a manner similar tothat by which the bonbon and `wrapper are forced into the mould, thesaid folding device being however provided with yielding lingers 66which will permit of the said device acting on bonbons of slightlydifferent sizes. rhe yielding fingers 68 are hinged to a cross-head 69on a rod 70 slidable in a socket "f1, mounted on a stud 72, projectingfrom the frame of the apparatus, the said rod 70 carrying anantifriction roller 73 which is caused, by a spring 75a, to bear on acam 74, secured to the shaft 64, which effects the reciprocation ofthesaid rod at the proper times. The socket 71 is oscillated on the stud 72by a cam 75, secured to the shaft 48, which actuates, through anantifriction roller 7 6, an arm 77 formed in one with the socket 71these being in accordance with the aforesaid prior patents, but inaccordance with the present invention there is pivotally mounted on, andreciprocable with, the crossheaol 69 a blade 78, which, upon the descentof the end-folding devices, acts to fold a projecting portion 79 of theend 57 of the wrapper onto the side of the bonbon, as shown in Figure 4of the accompanying drawings, which portion 79 acts to more securelymaintain the wrapper round the bonbons when the folding is completed.The movable side 50 of each mould adjacent to the blade 78, is of lesslength than the length of the partially wrapped bonbon, to permit theside portions 78a of the said blade to engage with the projectingportion 79, of the vwrapper and press the end portions thereof againstthe side ot the bonbon.

rlhe first end .told or the laterally projecting` ends ot the wrapperhaving been made, the second end folds of the said laterally projectingends 82 are made as the mould wheel continues to rotate by oscillatingarms 8O carrying at their ends folding' blades 8l, as shewn in Figures20, 2l and 22, oi? the accompanying drawings, the said arms being causedto engage, at the proper time, with the said proj ecting ends S2 ot thewrapper and lold it onto the iii-st end-itold. Each arm 8O constitutesone arm oitl a bellcrank lever mountedon a stud 83 and is caused tooscillate by acam 8a, secured to a rotatable shaft 85, and bearing` uponan antifriction roller 86, on the other arm 87 of the said bell-cranklever. il spring` 88, connected to the arm 87-and to any suitable iiXedpart ot the apparatus, maintains the roller 86 in engagement with thecam 84. Secured to the shaft 85 is a tooth-ed wheel 89 to which rotarymotion is transmitted from the toothed wheel 43 by the toothed wheels43a and 43h of the train ot toothed wheels hereinbefore mentioned.

lThe third end folds ol the laterally projecting` ends is effected byspring-pressed rotatable rollers 90 (preferably ot conical shape)carried by the before mentioned concentric plate, or guard, 91, betweenthe periphery of which rollers and the periphery ot'A the saidconcentric plate, or guard, the portions 92 of the said ends are foldedas the partially wrapped bonbon is carried round by the mould-wheel,

The wrapped bonbons are ejected from the moulds by the movable bottoms49 being caused to slide radially outwards in the mould, thereby'forcing the said bonbons out of the moulds onto a chute, ortravelliirg` band`or the like.` Each of the movable bottoms 49 of themoulds is provided with stems 93 adapted to slide in radial sockets 94Cin the mould-wheel and each is provided with an anti-*friction roller 95which, as thev mould-wheel rotates, is
